7.Astigmatism
If you have astigmatism in one or both eyes, your vision may be out of focus at any distance. It happens when the cornea, the clear “window” that covers the front of the eye, isn’t shaped right. Light rays can’t focus on a single point on your retina. Instead they scatter to many places. Glasses or contact lenses correct it. Surgery may be an option. Symptoms include blurred vision, headaches, fatigue, and eye strain.
8.Refractive Eye Surgery
Do you dream of seeing clearly without glasses? Surgery to reshape your cornea can correct nearsightedness, farsightedness, or astigmatism with a success rate of better than 90%. Surgery may not be right for you if you have severe dry eye, thin or oddly shaped corneas, or severe vision problems. Side effects include glare or sensitivity to light.
